title: Small round structured virus associated with an outbreak of acute gastroenteritis in Chiba, Japan.
abstract: In an outbreak of acute gastroenteritis which originated in a restaurant in Chiba, Japan, in December, 1987, small round structured virus (SRSV) particles were observed by electron microscopy in 14 of 16 stool specimens from patients. The particles were 30 to 35 nm in diameter, possessed amorphous surface structure surrounded by fine projections and had a buoyant density of 1.36 to 1.37 g/ml in cesium chloride. Serological responses to the SRSV were found by immune electron microscopy and Western blot (WB) assay in paired sera of 12 of 19 patients. Furthermore, WB analysis revealed that the antibody against SRSV was cross-reactive to other SRSV, Tokyo 86/510.
